You probably think you know how to take care of your teeth: brush twice a day and floss regularly, right? That’s certainly a good start, but there’s actually a lot more to keeping your teeth healthy. Follow these guidelines for better dental health.

The American Dental Association recommends brushing your teeth twice a day for a full two minutes, thoroughly cleaning all surfaces of the teeth. It sounds easy, but it can be difficult to stick to that guideline, and inadequate or irregular brushing can lead to plaque buildup, tooth decay, and periodontal disease.
